NAME

       plrgbhls - Convert RGB color to HLS

SYNOPSIS

       plrgbhls(r, g, b, p_h, p_l, p_s)

DESCRIPTION

       Convert RGB color coordinates to HLS

       Redacted  form:  General:  plrgbhls(r,  g,  b,  p_h,  p_l,  p_s)  Perl/PDL: Not available?
       Implemented as plrgb/plrgb1?

       This function is used in example 2.

ARGUMENTS

       r (PLFLT(3plplot), input)
              Red intensity (0.0-1.0) of the color.

       g (PLFLT(3plplot), input)
              Green intensity (0.0-1.0) of the color.

       b (PLFLT(3plplot), input)
              Blue intensity (0.0-1.0) of the color.

       p_h (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the hue in degrees (0.0-360.0) on the color cylinder.

       p_l (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the lightness expressed as a fraction (0.0-1.0) of  the  axis  of
              the color cylinder.

       p_s (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the saturation expressed as a fraction (0.0-1.0) of the radius of
              the color cylinder.
